Description

Detailed Description of the Invention

[0001]

The present invention relates to an oil fluorinated with at least one polysiloxane-polyoxyalkylene linear block copolymer, at least one water-soluble alcohol, and a non-volatile silicone in an aqueous medium. Or a novel cosmetic composition containing at least one insoluble conditioning agent selected from waxes.

[0002]

BACKGROUND OF THE INVENTION Sensitized to varying degrees by the influence of atmospheric constituents or by mechanical or chemical treatments such as dyeing, bleaching and / or permanents (ie damaged and / or embrittled). It is well known that hair is often difficult to untwist and style and is inflexible.

One of the commonly used methods for untangling and improving the softness of such hair consists of applying to the hair a cosmetic composition containing a conditioning agent.

[0004] In this regard, silicone, silicone derivative or fluorinated which can not only increase the flexibility and shine of treated hair but also easily detangle and style the treated hair. The use of additional cosmetic agents in the form of oils or waxes is popular today in hair and / or skin cosmetic compositions, especially those applied to sensitized hair.

[0005]

However, the use of such conditioning agents is not without problems.

First of all, in consideration of the property that the above conditioning agents are insoluble in an aqueous medium, it is necessary to use them in a dispersed form. In addition, non-volatile, insoluble conditioning agents, especially high molecular weight silicones, silicone rubbers or resins, have high viscosities and are particularly difficult to use in aqueous compositions.

Although it is known to emulsify silicones in the presence of surfactants, a number of parameters (surfactant nature and concentration,
It is necessary to consider the stirring method, temperature, etc.). Moreover, such preparation requires the use of large amounts of energy (stirring and / or heating).

It has also been proposed to add the above silicones to volatile silicones, the mixture having a low viscosity, but no dispersion in aqueous media. Dimethicone copolyols (CTFA name 5th edition, 1
It is also recommended to use silicones having surface-active properties such as 993) or mixed with volatile silicones for emulsifying non-volatile silicones, but the result is not sufficient. . The particles of the dispersion are coarse.

It can be said that, in general, the emulsifiers used hitherto lead to compositions whose cosmetic properties are inadequate.

It is an object of the present invention to facilitate the use of conditioning agents selected from non-volatile insoluble silicones or fluorinated oils or waxes in aqueous media, ie in such media,
The aim is to provide a novel means by which fine dispersions of these conditioning agents can be obtained.

Another object of the present invention is to provide a cosmetic composition having improved cosmetic properties, especially with regard to its ability to detangle and softness.

[0012]

In the applicant's company, by mixing a polysiloxane-polyoxyalkylene linear block copolymer with at least one water-soluble alcohol, a nonvolatile silicone in an aqueous medium is obtained. It has been found that an insoluble conditioning agent selected from the class and fluorinated oils or waxes can be readily dispersed. The dispersion obtained is fine and has good cosmetic properties. These are obtained by simple stirring and do not require the use of complicated equipment.
